ubifs_scan: corrupt empty space at LEB

Hi

Using NXP i.MX 6ULL (Digi ccimx6ul) and kernel 5.4.84, I get the following error when trying to mount a ubifs:

UBIFS error (ubi1:0 pid 910): ubifs_scan: corrupt empty space at LEB 104:118784
UBIFS error (ubi1:0 pid 910): ubifs_scanned_corruption: corruption at LEB 104:118784
UBIFS error (ubi1:0 pid 910): ubifs_scanned_corruption: first 8192 bytes from LEB 104:118784
UBIFS error (ubi1:0 pid 910): ubifs_scan: LEB 104 scanning failed
mount: mounting ubi1:update on /mnt/update/ failed: Structure needs cleaning

 

I've seen a couple reports of similar problems and some old patches, but they do not apply to recent kernel versions.

Is there something I can do to allow this filesystem to mount and recover at least some of the data?

Is there anything to do to prevent this problem from happening again in the future?

 

thanks
